Large-scale preparation method of transparent super-hydrophobic/super-amphiphobic coating

InactiveCN106800885AExcellent superhydrophobic/superamphiphobic propertiesHigh transparencySpecial surfacesCoatingsNanoparticle ComplexAlcohol
The invention discloses a large-scale preparation method of a transparent super-hydrophobic / super-amphiphobic coating. The method comprises the steps of ultrasonically dispersing nano particles into an alcohol-water mixed system and carrying out hydrolysis and condensation reaction on the nano particles and fluoride-free or fluorine-containing organosilane under the acid or alkali catalysis action to prepare a transparent suspension liquid of a fluoride-free or fluorine-containing organosilane polymer-nano particle compound; and applying the transparent suspension liquid of the compound on the surface of a substrate material through spraying or dip-coating to obtain the transparent super-hydrophobic / super-amphiphobic coating with good performance. Preparation of the transparent super-hydrophobic / super-amphiphobic coating of 10-100m<2> can be completed within an hour; large-scale preparation of the large-area transparent super-hydrophobic / super-amphiphobic coating is achieved for the first time; the preparation method is low in cost and simple in process; and the prepared coating has excellent super-hydrophobic or super-amphiphobic property, relatively good mechanical stability, chemical stability and environment stability, and has a wide application prospect.
